Thanks for the feedback! Since some you you guys asked here is a little more info...
He uses his guns for range/target shooting and hunting, but more range/target shooting. His two latest guns that need to get "pimped out" are...
Izhmash Saiga 12, 19" bbl (12 gauge)
CAI WASR-10, 16.25" bbl (7.62x39 mm)
He does already have a promag 20 round drum for the Saiga. Ideally I'd like to spend $100 or less, but I'm a little flexible in my budget!
BTW...I like to shoot too, but I dont know the lingo and all that fancy stuff. Just show me how to shoot it!
